RUPSE 150DB Air Horn, Car Horn for Truck Boats Car, Super Loud Train Horn, 12v Air Horns with Compressor, Airhorn for All 12 V Vehicles and Motorcycles

The media could not be loaded. The build quality is great - way better than I expected for the price. The horn is made of metal and feels sturdy, and comes with some easy mounting points. The air pump for it is also good and generates the air flow needed for the horn without any issues.I don't have a sound meter so I don't know how loud it actually is, but it sure surprised me when I powered it up for the first time. I was skeptical of the 150 dB claim, but I'm fairly certain that it actually reaches that if you were to measure right at the end of the horn. At any rate, it's easily loud enough for whatever you're planning to do with it.The sound of it is also great (see video). The 680 Hz specification had me somewhat afraid it'd be an annoying high-pitched sound, but it absolutely is not.I only wish they'd have included a relay - the air pump draws close to 20 amps at 12V, so it'll ruin any switch you connect to it pretty quickly. If you're able to work around that, I can only recommend this horn.

They were easy to install and when tested they were very loud. I had to extend the power cable as it wasn't long enough to reach the battery.I boughtva second set for another car and there was no wiring instructions. For anyone wanting to wire these in here's the wiring coloursRed 12v+ to batteryYellow to back of air hornsBlue is a negativeWhite to car current horns + wire.If your car uses the chassis as a negative you will need to run a negative from the air horns also. I just simply joined an extra negative wire and the blue wire to a mount point on the chassis.

Absolutely perfect , awsome tone 😊👍

Loud easy to install

It’s a well made horn and thankfully I wired it up to test before fitting. The relay didn’t release on switch off so it was returned.

Very good

loved this, its bigger (and much louder) than yo might think, one downside there were no wiring diagrams included with it, whih for someone like me who is not automobile profiicent would have been a great help. otherwise a great product and a VERY loud horn !!

Well made and loud
